Answer: The main features include energy efficiency, low pressure, oil-free operation, and water lubrication, providing pure compressed air suitable for industries with high air quality requirements.
Answer: The compressor is designed with advanced balancing techniques to minimize vibration and noise.
Answer: The GWL Series compressor can use either air-cooling or water-cooling methods, depending on the model and operating conditions.
Answer: It can be determined by observing the pressure differential indicator of the water filter or based on usage time and water quality.
A. Water lubrication B. Oil lubrication C. No need for lubrication D. Special lubricant lubrication Answer: D Analysis: Oil-free air compressors usually use special lubricants to cool and lubricate parts to ensure the purity of compressed air.
